Awesome vid amigo

For people using it, Don't pour a lot, little by little so it won't clog

Decent test. Old radiator, good sized holes. Thumbs up.

Great video. Bars leak saved me when someone hit and run the front end of my car and the busted radiator wouldnt hold any coolant whatsoever. The big key is if you are gonna take the radiator out to weld it or try and find leaks and leak area is found, then just replace the doggone thing. You already did the hard work of removing it.

Any vehicle with a good engine and good frame plus limited corrosion is worth working on.

Used car prices are too much.

My car leaks coolant so bad it only drives for 15 minutes before overheating 😂 I gotta keep gallons of water in my car to refill when I get to my destination to make it back

[kirksnyder]

This is one of the better test methods I have seen. I commend you on your efforts and observations.

I've used a couple raw eggs and about half cup of pepper in a few different squirting radiators. The egg cooks and scrambles in the hot antifreeze and the pepper will swell up to five times its size. Both the egg and pepper mix will coagulate wherever it's pissing from and seal up the leak. Smells like breakfast when you pop your radiator cap 😂😂 swear to god it works

I've used it for a 99 Ford f250 super duty with the 6.8 V10 gasser. It lasted a fairly long time, about 8 months until I pulled a heavy load. Honestly I wasn't to surprised when it stopped working under the extra exertion from pulling 10k. That's a bit much to ask of anything meant to be a temp fix and for a cost of under $10. Had I not pulled a heavy load, I have no doubt it would still be working.

Block sealants are really only a temporary repair, the only real fix is to fix the engine. Damage can result over the long term; a block sealant, i.e., Blue Devil, K W Block seal, etc may work in the short term and as such, is okay. But, they can also clog heater cores cause water pump problems etc. FYI -- I used KW Block seal (in the copper coloured can-- )on customers vehicle's for over 40+ years with good results. The trick with KW Block seal or any related product is to follow the instructions to the letter. Don't try and rush or shortcut the process; success or failure depends upon patience and effort.

I Have used it . I used it on a 2001Saturn SL2 to fix a bad head gasket, that was pissing out the side of the motor . My wife drove the car for another 60K miles with out adding any more coolant !

Thanks! I simply can't afford a radiator repair on my 2006 Honda CR-V right now, & DYI flushes have been banned in Cali from the last one I did in 2016, so this will really do the trick to buy me about 7 months time towards saving for an official repair!

ive used this to fix leaking timing covers, like a BAD LEAK. head gasket leaks... cracked manifold leaks. its awesome but not permanently the head gasket you have to use it again after 10k miles and it works

I've used it on a leaky heater core in my El Camino, it stopped the leak for a long time .

[nickmayfield]

I had a Altima with a blown head gasket, and it sealed it enough to keep driving a while

This is a great demo and of course the coolant system is under pressure and heat but hopefully no one is using this as a permanent fix. I’ve seen some cars with a spare tire for months on end and that’s not good especially when it’s the front tire.

I had a 2009 Pontiac Vibe with about 227k on the clock. The car still ran like the day I bought it.but I allowed a roommate to drive it to work and he ran the coolant dry. This in turned ruined my headgasket. I bought the bars to try and repair it, but unfortunately it threw a rod on me. Shockingly the crazy car still ran even with a hole in the block. but not very well.

[jeromecrockett]

I used this on my 1987 Cutlass and used it for years never had another issue

[jobfour]

Thats what I like a straight forward no nonsense verbiage

Just poured this same product in my Volvo 240 4 cylender which has a leaky freeze plug on the block. Ughhh. Hard job to fix. Poured the stuff in and it seems to work! so far so good.
One day in. Cheers from L.A. California.
